The basics of computer components

  1. 1. The Basics of Computer Components<br />by James Broadberry<br />
  2. 2. What I will cover<br />Processor<br />RAM<br />Hard Disk Drive<br />Graphics Card<br />Power supply<br />Motherboard<br />
  3. 3. Processor (CPU)<br />Brain of the computer<br />Controls everything that goes on<br />Every piece of information will go through the processor.<br />Every piece of logic is applied at the Processor<br />Speed of the processor is how many times the information can “cycle” through the processor.<br />
  4. 4. RAM<br />Temporarily stores information<br />Gets information to the processor without wasting/delaying clock cycles.<br />When the computer is turned off, the data stored in the RAM is erased<br />Adding more RAM will let more applications run faster<br />
  5. 5. Hard Disk Drive (HDD)<br />All files are stored on the Hard Drive<br />Slower than RAM but can hold more, permanently<br />The Operating System is stored on the Hard Drive<br />
  6. 6. Graphics Card (GPU)<br />Generates signals to be sent to the monitor/screen<br />Amount of pixels generated depends on the speed of the GPU and screen size<br />The rate that the pixels are “re-generated” or “refreshed” are measured in Hertz<br />
  7. 7. Power Supply (PSU)<br />Converts AC to DC<br />Power supplies for standard workstations are normally output about 350 Watts<br />Divide power up for safe use<br />
  8. 8. PSU Connectors<br />
  9. 9. Motherboard<br />All of the computer components are connected to it<br />Distributes power to the processor and RAM<br />Sends information between the Processor and the RAM<br />Gets between 30-40 degrees while doing nothing with correct cooling<br />
  10. 10. What goes where?<br />
  11. 11. Recap<br />Motherboard connects every component to each other<br />The processor does all of the logic<br />RAM stored information temporarily at very high speeds<br />Hard Drives store information permanently<br />Graphics Cards are used to generate a signal to be read and understood by a monitor<br />The power supply divides the power between each component<br />
